Configuration du DNS, du DHCP et des Interface reseau

  • Good evening everyone.
    I have a pfsense installed on my machine and I only configured the captive portal.
    the address of my freebox is
    Please help me to configure the DNS, DHCP and the different IP addresses to be entered on the WAN and LAN interface so that I have a stable internet connection.
    I do not want to do anything special on my network except share the internet connection by forcing customers to connect via the captive portal.
    Thank you in advance.
